If one teaches astronomy, should one also teach astrology? or if teaching chemistry, should one also teach alchemy? If a student is preparing to become a brain surgeon, would alchemy develop adequate skills? or if studying astrophysics, would astrology provide proper background?

Rationales for not believing in any astrology, alchemy or creationism include the lack of empirical evidence, the existence of evil, the argument from inconsistent revelations, the rejection of concepts which cannot be falsified, and the argument from nonbelief.

The burden of proof of the atheist is not to prove evolution, but on the theist to provide a rational for creationism.
